High skirt TO 58 Deep silver pasteurizable lid - Pack of 30 units

01 · COMPATIBILITY

The TO figure names the mouth, not the jar's outside diameter

TO 58 is the name of the Twist-Off mouth, on a GPI 2020 profile, with four closing lugs. Measuring the outside of the jar tells you nothing: a jar of similar diameter but with a different number of lugs or a different mouth height will not close properly, and you only find out when it loses vacuum. This version is deep skirt: the skirt covers more of the jar neck, so it only goes on jars meant for that profile. From our catalogue, it fits the TO 58 jars: Ánfora 212 ml, Osito 285ml.

02 · PASTEURISATION

The limit belongs to the lid, not to the whole process

The datasheet declares pasteurisation up to 100 °C for 60 minutes. That figure says what the lid withstands, not that any heat treatment is validated: temperature, time, vacuum, sealing compound, product and jar are validated as one system. And within a single run it is unwise to mix lids from different batches or profiles.

03 · STORAGE

What degrades is the sealing compound

The gasket that seals against the glass is the delicate part, and it goes before the metal does. Keep the lids in their packaging, clean and dry, between 5 and 35 °C and below 70 % relative humidity; the documentation sets two years as the maximum unless specifically approved. Avoid knocks on the skirt and stacks that deform the lugs: a bent lug will not seal even if the lid looks intact.

04 · BEFORE YOU BUY

The sales unit is 30 silver deep-skirt lids. Before ordering, check your jar's mouth: the TO reference is what governs.
